Researchers from Diponegoro University used closed chambers to extract gas samples GROBOGAN, INDONESIA - A recent rice field study in Central Java, Indonesia, found that integrating biochar into conventional farming practices reduced total greenhouse gas emissions by up to 80 percent, while also increasing crop yields. The emissions reduction was driven primarily by lower methane output. Methane potential declined from 4,545 to 803 kg CO₂-equivalent (CO2e) per hectare in bioc

Biochar and charcoal look similar and are produced through related thermal processes, oftentimes causing confusion on the difference between the two. At first glance, they appear to be the same black, carbon-rich substance. However, when you examine their purpose, production processes, and impact on the environment, soil, and human use, the differences become clear and highly significant. This article will explain the differences between biochar and charcoal in various aspect

JANUARY 2026 - WasteX has been selected as one of 19 suppliers in a Salesforce-backed purchase via Milkywire , contributing to a global portfolio of more than 12,500 tonnes of durable carbon removal. The pre-purchase initiative, facilitated by Milkywire, is designed to provide early-stage capital to high-integrity carbon removal projects with long-term mitigation potential. WasteX contributed 1,167 tonnes of durable carbon removal to the portfolio, reflecting confidence in th

JANUARY 2026 - WasteX is working with Universitas Tribhuwana Tunggadewi ( UNITRI ) to support the development and wider adoption of biochar in Indonesia. The collaboration strengthens WasteX’s ongoing engagement with industry players, government institutions, and non-governmental organizations to support climate-resilient and sustainable agricultural systems in the country. The collaboration was initiated through a guest lecture and podcast session, serving as the first step

Biochar  is a carbon-rich material with a highly porous structure, making it well suited for trapping contaminants, reducing pollutant loads, and improving water quality across a range of treatment contexts. Its resistance to biological and chemical breakdown allows biochar to perform reliably over long time horizons, whether used in water treatment systems, stormwater management infrastructure, or decentralized treatment setups. Why Biochar Works for Water Filtration Let’s t

Mining activities often leave behind compacted soils, low organic matter, acid mine drainage , and elevated concentrations of heavy metals. These conditions make natural revegetation slow, expensive, and uncertain.  Biochar , a carbon-rich material produced from biomass through pyrolysis, offers a practical and science-backed tool to accelerate ecological recovery while supporting long-term soil health. This article explains how biochar works in mine reclamation, why it is ef

As the construction industry accelerates efforts to cut CO2 emissions, researchers are turning to biochar , a carbon‑rich material derived from organic waste, as a high‑value additive to concrete composites.  This shift is driven by the need to reduce reliance on Portland cement , whose production is responsible for nearly 8% of global greenhouse gas emissions  due to the energy-intensive production process and the calcination of limestone. Studies highlight how adding biocha

The choice of feedstock is one of the most critical factors in determining the quality, stability, and performance of the resulting biochar . It determines the specific properties, potential contaminants, higher carbon contents, and even the environmental impact of the final product. This guide outlines the key types of feedstock, how pyrolysis temperature shapes the final material, and the main factors to consider when choosing sustainable, low‑contamination biomass for prod

JAKARTA, INDONESIA - A policy seminar on 12 November brought renewed attention to the role of biochar in improving the performance and resilience of Indonesia’s rice sector. The event, hosted by the Embassy of Denmark in Indonesia together with the Ministry of National Development Planning ( BAPPENAS ), emphasized the need for practical, scalable solutions that support food security and climate goals. During the seminar, WasteX presented new field evidence showing that conver

The deep litter system is one of the most widely used and cost-effective housing systems in poultry farms.  This method relies on allowing bedding materials to build up over time instead of removing them daily, creating a composting layer that benefits both the birds and the farmer. In this guide, we will explore how the deep litter method in poultry works, the best litter materials to use, how thick the bedding should be, the challenges, and how proper management can boost p

Roots are one of the most essential parts of the plant, yet they often go unnoticed because they grow beneath the soil.  When people ask, "How do roots help a plant?" the simplest answer is this: roots give the plant strength, stability, and life. They perform critical functions such as anchoring the plant, absorbing water and dissolved minerals, storing food, and supporting overall growth. But the full story is far more fascinating. In this article, we'll explore how roots h

Choosing the right approach in applying biochar ensures that it delivers maximum impact: whether your goal is soil amendment, boosting water and nutrient availability, or contributing to climate-positive agriculture. This comprehensive guide explains the best ways to apply biochar, how to select the right application rate, and how different techniques will depend on your farming conditions. What Is Biochar and Why Does Application Method Matter? Biochar is a stable form of c

Soil pollution is a growing environmental issue that affects food security, human health, and the long-term sustainability of agricultural and urban landscapes. As human activity increases, so do the toxic substances, chemical pesticides, plastics, and industrial waste that seep into the ground.  This comprehensive guide explains the common causes of soil contamination, the effects of soil pollution, and practical solutions—both natural and technological—to reduce soil pollut

Biochar and compost are powerful soil amendments. On their own, each brings significant benefits. But when combined, they are more powerful in enhancing productivity, supporting long-term soil health, and contributing to sustainable agriculture.  This article explores the benefits of using both materials, how biochar and compost work together, and how to blend them to get the maximum benefits. Why Combine Biochar and Compost? Though compost alone enriches the soil, pairing i

Biochar trials in Indonesia boosted cauliflower yields 29% and bitter gourd 70%, raising farmer income while cutting fertilizer use.

Unlike most organic matter added to soil, biochar  is not designed to decompose quickly. Its value lies precisely in its persistence: both in how long it continues to influence soil functions and in how long the carbon it contains remains stored in soils.  To understand this longevity, it is necessary to look at historical evidence and long-term scientific research rather than short-term crop responses alone. Let's dive into this right away! How Long Does Biochar Last in Soil

GROBOGAN, INDONESIA - WasteX has joined hands with Indonesia’s Ministry of Agriculture to bring biochar into the nation’s Climate Smart Agriculture (CSA) program. The initiative highlights how WasteX's biochar solutions can improve food security while helping farmers adapt to climate change. The first project site of the program is in Grobogan, Central Java, a key rice-producing region now facing soil degradation and unstable weather. For this program, WasteX has supplied 10

WasteX’s biochar programs in Indonesia have achieved a new milestone. In July 2025 alone, WasteX mitigated an estimated 131 tons of CO₂e. This figure is based on biochar production in July and its expected application in agriculture. Once applied to farmland, biochar creates a multi-layered positive impact on the environment: Carbon removal and storage (>1,000 years):  Long-term, stable carbon locked in soils. Carbon removal and storage (<1,000 years):  Medium-term storage of

WasteX presenting biochar as a solution for food loss and waste problem in Indonesia JAKARTA, INDONESIA - At the recent Food Loss and Waste Policy Dialogue  hosted by P4G Partnerships and Bappenas (Indonesia’s Ministry of National Development Planning), discussions centered on Indonesia’s targets to cut food waste in half by 2030 and achieve food security by 2045. WasteX presented biochar as a practical solution: converting agricultural residues into a resource that can simu
